While driving on the interstate, the engine shut down, no warning, or codes. I have had trouble with IPR clogging in the past, engine cranks fine, just won't fire. Scanner says no hop to fire injectors. I have commanded the valve open and closed, and it appears to be moving. My question is, if its clogged, would that cause a no start? I have had the valve replaced three times now. 2006' f350' new injectors, egr delete, new turbo, new oil cooler, new exhaust, edge with attitude cts. Any advise is appreciated.

When I got truck, it had been neglected.... The oil filter had come apart from not being changed when needed. There was a large amount of crude built up in side, it is going away after many oil and filter changes, but has still caused a lot of grief. When the oil cooler was changed, we did replace the screen as well.

OK, so we pulled the IPR valve, small tear in screen, some trash on it as well, but not neaqrly as bad as I would have thought. Replaced it with a new valve and she fired right up. This is another one out the window. Not sure where the trash is coming from, or how much more there is..... I dont want to keep replacing this thing every 5-6k miles..... Thanks to everyone that helped.

From all I have been reading, if the trash or debris is metal, then YES, the pump is failing most likely. Mine is not metal, just sludgy oily crude. I was told the truck went over 50,000 without an oil change, and at one point, the filter had come apart. I have changed the oil every 4000 for the last twenty now in hopes of cleaning it out. I'm a little scared of trying to flush it with something, in fear it may break too much loose at once, and then I will be chasing cloggs everywhere. Any advice from anyone else on this issue is truely appreciated.
